Claims.

This invention relates to a jig for carrying and holding fiat parts such as head and foot boards of beds, and supporting them in positions where they may be carried through a finishing process on supporting pallets, to which the jigs or fixtures are detachably secured.

It is an object and purpose of this invention to provide a readily removable jig which may be attached to standard finishing pallets to accommodate head and foot boards of any of the sizes of beds, and hold and retain them within the outlines of the pallets in position such that any or all the finishing operations to be performed may take place on head and foot boards, without removal from the carrying jigs or any change of position thereon.

It is a further object and purpose to provide a jig of the type noted on which a head or foot board, either one or both, or a plurality of them may be carried,- all surfaces requiring finishing being readily reached by a spray gun and no defects left to mar exposed surfaces. Furthermore such jigs are of simple, sturdy and economical character and are readily produced for the purposes for which they are to be used.

An understanding of the invention may be had from the following description, taken in connection with the accompanying drawings, in which,

Fig. 1 is a side elevation showing the mounting of a jig on a pallet, the pallet being shown in end view.

Fig. 2 is a perspective view of one of the head and foot board holding members, a plurality of which are used in practice with each jig.

Fig. 3 is a transverse section, enlarged, on the plane of line 3-3 of Fig. 1.

Fig. 4 is a perspective view showing two of the jigs detachably mounted on a pallet and spaced fromeach other, as they are used, and

Fig. 5 is an enlarged, generally vertical section, substantially on the plane of line 55 of Fi 3.

Like reference characters refer to like parts in the different figures of the drawings.

7 A standard pallet I of generally rectangular outline, and which is horizontally located when in use, may have at its opposite longitudinal edges notches or recesses therein for the location of the jigs which are to be detachably secured. As many of such notches or recesses in pairs, as may be wanted will be provided in such longitudinal edges. In the structure shown in Fig. 4, two pairs of the notches or recesses, one adjacent each end of the pallet at which the jigs are detachably secured are shown.

Each of the jigs include a flat horizontal lower bar 2 of'metal which, at what may be termed its rear end, is bent downwardly, as at 3, and terminates in a forwardly extending lip to provide a hook to seat in a rear recess at the back edge of the pallet. At the front edge of the pallet a generally verticaljaw member 4 has, at its lower end, a lip 5 turned to the rear for engagement with the pallet at the forward notch or recess of the pair of notches in which the rear hook 3 of the bar 2 is located. Such member 4 is pivotally connected above the pallet, at 6, to a vertically extended member 1 integral with and at the front end of the bar 2. The member 4 through its pivotal connection at 6 may be manually actuated to release the jig when wanted. The pivoted member 4 is acted upon by a spring, shown partly in Fig. 1, to normally swing the lower part of the jaw into pallet engaging position.

An elongated bar 8 extends upwardly and to the rear from the front end ortion of the horizontal bar 2. A second shorter bar 9 extends from the rear end portion of the bar 2 toward the bar 8, engaging it substantially midway between the ends of the bar 8, and is permanently secured thereto by welding or other suitable means. The bars 8 and 9, at their lower ends, are connected with the bar 2 by welding or otherwise and are reinforced by plates II] as shown.

The bars 8 and 9 are of a generally channel form in cross section, each having a web II, and two spaced parallel flanges I2 extending therefrom, each of which terminates inan inwardly The bars 8 and turned elongated lip I3 (Fig. 3). 9 when the jig is on a pallet, have the webs II preferably located at their inner sides as shown in Fig. 4.

On each of the channel bars 8 and 9 a number of fixtures are mounted for adjustment to different positions. Each is made from a plate of metal I4 which at one end has an inturned tongue I5. The tongue I5 near its juncture with the plate I4 is recessed at opposed edges, as at I6. Also said tongue I5 at opposite edges is beveled as best shown in Fig. 5.

At the opposite end of the plate l4, a narrow width of metal is turned at right angles in the same direction as tongue I5, providing an arm H which terminates in an extension I8 at right angles thereto (Fig. 2). Such fixture I4 or a number of them, may be mounted upon bar 8 or 9 by inserting the tongues l5 in the slots between the adjacent edges of the lips I3, a fixture occupying substantially the position shown in dash lines in Fig. 5, and after the tongue has been inserted, turning ,itto the full line position, whereupon the lips I3 extend into the recess at I6 and the sharpened edges at opposite side edges of the tongue I5 bite into the flanges l2 at the inner sides thereof, to hold the fixture at any position selected in the length of a bar 3 or 9 on which it is mounted. When turned to the full line position, in Fig. 5, the arm I! extends across the upper flange l2 of the bar to which attached, with the terminal section It extending downwardly at the inner side of the web ll. 7

The plate I4 of the fixture, substantially midway between its -ends and-at its.;outer edge; has

a narrowed portion :9 which, at its end and at one side edge, is provided with a pointed or wedge shaped projection 28.

at 2|, and at the end of the fixture M nearest Spaced a short distance from said projection 20, and below it, is a hump.

the arm I! another raised humpzfis provided as shown.

In Fig. 1, in dash lines, a plurality of footboards" are shown carried at the front of the bars 8 of two spaced jigs which are detachably mountedon the pallet, with the foot boards betweentwo. of the adjustable carryingfixtures H5 therefor on each bar 8. The lower ends of the legs of a foot boardare engaged against and may be: slightly penetrated'by the-pointed wedgesorj'tangst 202" mostfixtures; while atthe upper end""of the' foot" board'it rests against the humps 22" of the .next
